Abstract
Effect of dietary supplementation of sodium butyrate and / or protexin on the growth
performance, some blood parameters, and immune response of oreochromis niloticus
Ahmed H. A. and Sadek K. M
Two hundred Oreochromis niloticus fingerlings were used to explain the effects of
supplementing a basal diet with sodium butyrate (SB) and / or protexin on the growth
performance, some blood parameters, body composition, and immune response.
Oreochromis niloticus fingerlings were allotted into 4 experimental groups. The control
group (1) was fed the basal diet (BD), while group (2) was fed BD with SB at level 3 g/ 10
kg diet, group 3 fed BD plus protexin (probiotic) 1 g/ 10 kg diet and group 4 was fed BD
with SB and protexin at 3 and 1 g/ 10 kg diet. Results obtained showed that the highest
growth (final weight, total weight gain and SGR) of Nile tilapia were obtained with feeding
diet containing SB plus probiotics followed by SB (group 2) supplemented diets (P<0.05)
1
when compared with those of control group. The best FCR values observed in SB plus
Protexin-supplemented diets. The results revealed that, probiotic nonsignificantly increased
blood glucose and intestinal glucose absorption while sodium butyrate significantly increased
blood glucose level, intestinal glucose absorption and both probiotic and SB supplementation
have no any adverse effects on liver functions reflected in normal blood protein pattern and
enzymatic activity. We concluded from this study that using of SB and SB plus probiotic is
preferred for good performance in tilapia fish production because the beneficial effect of
butyric acid on the proliferation of the intestinal epithelium.

Abstract
Three hundred and sixty un-sexed one day old of Japanese quail chicks were used
in this study to investigate the effect of dietary supplementation of Entrococcus
faecum and Lactobacillus containing probiotics (Protexin® and AM Phi- Bact)
respectively, at 0.1 g/kg and 0.325 g/kg and/or MOS or β-glucan plus MOS
containing prebiotic (AGFLO® and Alphamune) respectively at 0.5g/kg for each
one compared with control diet for 9 respective groups (45 birds/group) on growth
performance, immune response, some blood parameters and carcass traits of
Japanese quail chicks. At the end of experiment it was observed that Entroccus
faceum or Lactobacillus containing probiotics and/or MOS or β-glucan plus MOS
containing prebiotics (groups 2 – 9) supplementation non significantly (P≥0.05)
improved final body weight and total body gain of quail chick by about (0.3% and
0.5%), (1.5% and 1.8%), (1.2% and 1.4%), (2.5% and 2.7%), (3.9% and 4.3%),
(2.1% and 2.3%), (0.9% and 1.1%) and (1.4% and 1.5%) respectively when
compared with the control. Concerning total feed intake it was observed that
probiotic (containing Entrococcus or lactobacillus) and prebiotic (AGFLO only)
supplementations (groups 2 – 4) slightly increased total feed intake by about 1.7%,
0.75 and 1% respectively, while supplementation of Alphamune prebiotic and
combination between probiotic and prebiotics (groups 5 – 9) reduced total feed
intake during the whole experimental period by about 1.7%, 4%, 6.8%, 5.7% and
6.4% respectively when compared with the control. Lower feed intake and improved
gain reflected on significantly (P≤0.05) improved average FCR throughout the
experimental period when compared with the control. It was observed that bacterial
probiotics reduced phagocytic activity and improved phagocytic index while MOS or
β-glucan plus MOS prebiotics improved both phagocytic activity and index in quail
chicks when compared with the control. Moreover Supplementation of MOS alone
or combined with bacterial probiotics more effective for production of antibody titer
against New castle disease than bacterial probiotics supplementation alone
especially toward the end of the experimental period. It was observed that
combination between probiotics and prebiotics (groups 6 -9) significant improved in
total protein, albumine and globulin and decreased GPT and triglycerides serum
concentrations when compared with the control. Moreover, treatment had no
significant effect on dressing%, liver, heart and gizzard relative weight when
compared with the control. While bacterial probiotics had adverse effect on relative
weight of some immune organs.

Abstract
Experiment was conducted using 500 ducks of day-old (300 Muscovy
and 200 Moulard) Sexing was done for ducks at the first day of age, then the
experiment was completed on males only (180 Muscovy, 120 Moulard),
where it was brought up in accordance with the principles of the French care
for birds research and rearing of water fowls for fattening purposes until 12
weeks of age. At this age birds were divided within each breed according to
feeding regime (forced feeding and ad libitum feeding group), and addition
of L carnitine by 1000 mg \ kg of feed (L carnitine and non L carnitine
group) making eight groups until the end of the study (at 14 weeks).
The results of the experiment revealed that, forced feeding has a
significant increase in body weight and absolute or relative weight gain
(5954.33 g, 1421.03 g and 23.51%, respectively) than ad libitum feeding
(4506.75 g, 411.05 g and 8.94%; respectively). Under the regime of forcefeeding Moulard ducks had significantly increase in absolute and relative
body weight gain (1808.16 g and 29.64%, respectively) than Muscovy ducks
(930.67 g and 15.73% respectively). Feed conversion per kg increase in
weight was the best in Moulard ducks than Muscovy under force-feeding
regime (6.29 kg and 11.5 kg, respectively), and vice versa with the ad libitum
feeding (18.89 for 11.06 kg, respectively), at the same time the Moulard
ducks needed a larger amount of feed per kg liver, (in forced or ad libitum
feeding) than Muscovy.
Force-feeding led to severe assembly of fat in the liver, which was
significantly higher than in ad libitum feeding groups (57.78% from 35.28%,
respectively) and on the contrary, was the percentage of protein (9.66% from
28.81%, respectively). Addition of L carnitine to the feed at forced feeding
period resulted in a significant increase in the life weight (5731.97 g) than in
non L carnitine fed group(5400.13 g), on the other hand other performance
traits not affected significantly by the addition of L carnitine in feed. Liver
weight (absolute and Percent) in L carnitine treatment group was higher than
non L carnitine group in the ad libitum feeding group but it was not
significant. Using L carnitine in ad libitum feeding groups achieved a higher
percentage of dry matter in liver (30.88%) than those without L carnitine
(28.98%), unlike the chest muscles; dry matter was higher in the group
without L carnitine than with L carnitine (32.05% from 30.37%). The
composition of the liver and the muscles under the system of forced feeding
with L carnitine than those feed without L carnitine. We concluded from this
study that using of Moulard duck is preferred for the foie gras production
than Muscovy ducks because of its ability to receive large quantity of feed
and has the highest feed conversion and a better feed per kg increase in
weight as well as the absolute and relative weight of the liver from Muscovy
ducks under the forced feeding regime. L carnitine has no effect on the foie
gras production, but if it was added to the feed during the forced feeding
period it improved live weight significantly.
